Is there a similar figure for specificity i.e the number of truly unrelated pairs that are not matched by the algorithm. In other words, what is the chance that a detected match by the algorithms (say for 4th cousin) is actually a "false positive" and the two are in fact unrelated (or much more distantly related). In medical diagnosis it is important to compute both sensitivity and specificity.<br />Iainhttps://www.blogger.com/profile/04685228974985888660noreply@blogger.comtag:blogger.com,1999:blog-4773058005679938889.post-25006174190408718532014-04-05T14:42:01.788-07:002014-04-05T14:42:01.788-07:00I am descended from Terrence Travis, (1805-1902) w...I am descended from Terrence Travis, (1805-1902) who moved from Manorhamilton, County Cavan, to Leeds with his wife Mary McCann (1820-1902). Their children were Catherine, James, John, and Terrence. They came to Chicago when their children emigrated in the 1860s.

It was interesting to see how they differed. I share 54.30% with my sister, 31.39% with one paternal half sister and 23.67% with the other (this was the most surprising!), 24.64% with my paternal aunt, 14.85% with my dad's double first cousin, and 10.18% with my maternal great uncle.<br /><br />I still have four kits from DNA day to give away: one is going to another one of my dad's double cousins, two are going to my maternal aunt & uncle, and one is going to a maternal great aunt. I really need to get on that and talk everyone into spitting :)Andreahttps://www.blogger.com/profile/16858480399075402560noreply@blogger.com
